Question

{ [ ( - 3 elevado a 3) . ( + 2 elevado a 2 ) + ( -3 ) ] + 100 } :raiz quadrada de 121 =?

Answer 1

{[(-3³).(2²) + (-3)] + 100}÷√121   --> -3³ = -3x-3x-3 = -27 --> 2² = 2x2 = 4

{[(-27).(4) -3] + 100}÷/√121        --> -27x4 = -108            --> √121 = 11

{[-108-3]+100}÷11                     --> - 108 - 3 = -111

{-111 + 100}÷11                        --> -111 + 100 = -11

-11÷11                                       --> -1

Resposta = -1
